Android Send verification code countdown effect and automatically get verification code and fill in the input box

In the registration, real-name authentication, modification of mobile phone number, we will use the function of sending verification code, here will often involve 2 effects,

First: Send a verification code countdown effect;

The second one: Automatically gets the received SMS and fills in the verification code.

First, the countdown effect:

It's really simple, it's a timer. Refresh every second, the countdown is finished. You can re-click to get it.

<pre name= "code" class= "Java" >btn_getyzm.setenabled (false); Btn_getyzm.setbackgroundresource ( R.drawable.daojishi), task = new TimerTask () {@Overridepublic void run () {Runonuithread (new Runnable () {//UI Thread@overr idepublic void Run () {if (time <= 0) {//When countdown is less than 0 o'clock remember to restore the picture, you can click Btn_getyzm.setenabled (true); Btn_ Getyzm.setbackgroundresource (R.drawable.btn_yangzhengma_selector); Btn_getyzm.settextcolor (Color.parseColor ("# 454545 ")); Btn_getyzm.settext (" Get Verification Code "); Task.cancel ();} else {Btn_getyzm.settext (time + "seconds after Retry"); Btn_getyzm.settextcolor (Color.rgb (125, 125, 125));} time--;}});}; Time = 60;timer.schedule (task, 0, 1000);

Second, automatically listen to new text messages, and parse the inside of the Verification code

Trim (). toString (); if (verifytext! = null && Amp Null!=smscontent &&! "". Equals (smscontent)) {verifytext.settext (smscontent); Verifytext.setselection (Smscontent.length ());}}}}
